After amplify DNA template using PCR method, now you can continue your work by using gel electrophoresis in a gel composed of agarose in order to separate DNA fragments based on its molecular weight. The percentage of agarose used depends on the size of fragments to be resolved. In general a 0.8-1% gel may be …

You must have known that agarose gel electrophoresis is generally adequate for resolving nucleic acid fragments in the size range of 100 nucleotides to around 10-15 kb. But, for nucleic acid which its fragments below those range, it will be difficult to separate and hard to visualize because of diffusion within the gel matrix. These …
